Kellogg Company: Bulk packaging of cereal: Stretch wrapping

Consisting of a corrugated bottom sheet, a pre-made flexible-film bag, and stretch film, the K-one system replaces a corrugated bulk box and flexible film liner.

Like that packaging format, the K-one bulk pack is used by Kellogg to move cereal from where it's processed to where it's packaged, whether in-house or at a contract packager. As cereal height rises sensors detect it and signal the stretch film carriage to begin wrapping.
